Oil prices suffered their biggest selloff in five months on Monday, falling as much as 8 percent as Greece's rejection of debt bailout terms and China's stock market woes set off a deepening spiral of losses.

U.S. Rig Count is up 3 rigs from last week to 862, with oil rigs up 12 to 640, gas rigs down 9 to 219, and miscellaneous rigs unchanged at 3.

Worldwide, job cuts from the oil bust reached a staggering 150,000 at the end of May, according to energy recruiting firm Swift Worldwide Resources. However, some analysts believe the worst is over, and by the end of the year, the US could see a stout recovery. Analysts tend to agree that a slowdown in non-OPEC production, led by U.S. shale producers, and unrest in the Middle East and North Africa, particularly Iraq, would support prices this year.

Russia has been hit by lower oil prices and by Western sanctions over its role in the Ukraine crisis. Its rouble currency fell sharply against the dollar in 2014 and has yet to recover.

Shale output in the United States will prove resilient to low oil prices likely to be prolonged by the prospect of half a million barrels per day of Iranian crude making its way back to the market.

Booming U.S. shale production helped cut OPEC’s global crude market share to a 12 year low last year.

China's apparent oil demand* in May increased 8.2% from a year earlier to 43.80 million metric tons (mt), or an average 10.36 million barrels per day (b/d).

Greece moving down oil prices. Oil prices fell on Monday, with U.S. crude dipping below $59 per barrel to an almost three-week low, after Greece imposed capital controls as lenders refused to extend the country's bailout.

Natural gas faces growing competition from coal and renewable energy sources at a time when its potential demand growth is slowing down, an International Energy Agency official said. “The last large contracts for [LNG] were signed in 2014 just before oil prices collapsed. We believe it is still competitive, but there are risks,” said Laszlo Varro, who heads IEA’s gas, coal and power markets division.

Share sales by US oil and gas companies have slowed sharply in recent months, in a sign of the tightening financial pressures on the industry following the fall in crude prices.

Выручка от реализации составила 1 288 млрд руб. (21 млрд долл. США). На фоне снижения мировых цен (-12% в рублевом выражении по отношению к 1 кв. 2014 г.) эффективное распределение ресурсов и использование высокомаржинальных каналов реализации позволили скомпенсировать снижение выручки, составившее 6,3% по отношению к 1 кв. 2014 г.

According to a recent report from Swift Worldwide Resources, over 150,000 jobs in the global oil and gas industry have been cut since oil prices began to tumble last summer.

U.S. was keeping the European Union countries on a 'short leash' by forcing them to impose anti-Russia sanctions.

Russia could not provide Ukraine with the gas price discount it once had, days before new gas talks between Russia, Ukraine and the European Union.

Iran produces about 2.7m barrels of oil a day. But a report by Wood Mackenzie, the energy consultancy, to be published on Thursday, says that it could add 600,000 b/d of crude production by the end of 2017, assuming that it strikes a nuclear deal with the US and EU that lifts sanctions.
